SJ6025N1ARP

Scrs Overview

The Littelfuse SJ6025N1ARP is a high-temperature Silicon-Controlled Rectifier (SCR) from the SJxx25xxA series, designed for uni-directional switching applications. It features a TO-263AB (D2-Pak) surface-mount package with an RMS on-state current rating of 25 A and a maximum junction temperature of 150°C. The device offers a rated repetitive peak off-state voltage (VDRM/VRRM) of 600 V and supports surge currents up to 350 A at 60 Hz. Gate trigger characteristics include a maximum IGT of 6 mA and a typical VGT of 1.5 V. It is AEC-Q101 qualified for automotive Level manufacturing control.

Scrs Feature Summary

• High thermal endurance with a maximum junction temperature of 150°C
• Sensitive gate design enabling direct interfacing with microprocessors
• Robust surge capability supporting high inrush current demands
• Automotive-grade qualification ensuring reliability in demanding environments

Scrs Applications

• AC Generator (ACG) rectifiers
• Battery voltage regulators
• Inrush current controllers in AC to DC applications
• Soft starters for low power AC motors
• Controls for power tools and home appliances

Scrs Procurement Notes

Verify the specific ordering suffix 'RP' confirms the embossed carrier reel packaging format rather than standard tube packing. Confirm that the component meets RoHS compliance standards and halogen-free requirements as specified in the datasheet. Ensure the selected part number aligns with the required voltage and sensitivity parameters for the intended circuit design.

Scrs Selection Notes

Select this component when surface-mount assembly is required for high-current SCR applications. The TO-263 package provides efficient heat dissipation suitable for compact designs. Consider the 6 mA gate sensitivity for low-power drive circuits. Verify that the 600 V blocking voltage exceeds the peak line voltage plus transients in the target application.

Scrs Part Context

This device belongs to the SJxx25xxA series of 25 Amp high junction temperature SCRs manufactured by Littelfuse. The series includes variants with different voltage ratings (400 V or 600 V), gate sensitivities (6 mA, 10 mA, or 35 mA), and packages (TO-220L, TO-220R, TO-263). The SJ6025N1ARP specifically denotes the 600 V, 6 mA sensitive, TO-263 variant.

Scrs Replacement Considerations

Direct replacements within the same family include SJ6025N2ARP (10 mA sensitivity) or SJ6025N1TP (tube packaging). Cross-package equivalents like SJ6025R1A require mechanical adaptation. Verify thermal resistance differences between TO-263 and TO-220 packages during substitution.
